Bodybuilders, amateur weightlifters, and athletes have started using SARMs – it’s a way of losing fat, building muscles, and increasing strength in the gymnasium. 

Just in case you’re new to the SARMs world, you would know how hard it is to choose the best one for your cycle. SARMs have the same characteristics, but you shouldn’t assume they’re all the same. 

RAD140 and Ostarine (also called MK-2866) are both SARMs, but they both have different results, side effects, and recommendations of dosage. Here’s a comprehensive guide that compares two of these SARMs and gives you clarity about which one’s better for your body goals. 

How are RAD 140 and Ostarine Different from Each Other?

Here are the key differences between Rad 140 and Ostarine: 

  • RAD 140 is meant for advanced users, whereas Ostarine is meant for amateurs or begiernns.
  • RAD 140 is suitable for bulking, and Ostarine is utilized for cutting.
  • RAD 140 gives you major side effects as compared to Ostarine. Ostarine can be tolerated quite well.
  • RAD 140 isn’t recommended for women, whereas Ostarine is.
  • The average dosage of RAD 140 should be 5 to 15 mg per day whereas Ostarine is 25 mg per day.
  • RAD 140 is costlier than Ostarine.

Now that you are aware of the significant differences, let’s find out what is unique about each of these SARMs. This will give you an idea about the SARM that’s ideal for you.

One of the Most Potent SARMs – RAD 140 (Testolone)

RAD 140 is the stronger one of the two. It’s also called, ‘Testolone.’ RAD 140 is considered one of the most potent SARMs you can find.

Out of all the SARMs available today, Testolone is closely compared with steroids – and the credit goes to the potency. 

As per researchers and users, a 5 to 30 mg dose on a daily basis for 6 to 8 weeks will be good enough for most of the weight lifters.

Beginners should start with 5 to 10 grams; intermediates can opt for 20 grams a day. 

It leads to lean muscle gain of about 10 lbs or 4 to 5 kilograms in one single cycle. You need not increase the dosage as Testolone is a strong and potent compound. A small amount will work brilliantly. 

As per research, RAD 140 leads to better, speedy muscle growth. Bodybuilders can gain about 10 to 15 lbs of muscle from an 8 to 12-week cycle.  

The downside of Testolone is the unknown side effects. There is very little information on the side effects caused by RAD 140. 

It’s a strong compound, so be sure not to increase the dosage as the side effects are unknown as of now. RAD 140 is rarely used in the cutting phase (or when you are trying to lose weight). 

If you’re just starting out and have no idea about SARMs, it is best to avoid RAD 140 because it is highly potent. A milder compound like Ostarine is best for those who are experimenting. Keep reading to find out the definitive benefits of Ostarine.

Reap Solid Benefits with Ostarine (MK-2866)

Ostarine is also called, ‘enobosarm.’ It was developed by Merckx, but the production is being handled by GTx. The pharma company is based in Memphis and it is a small one indeed. 

Ostarine is quite popular, but for the opposite reasons to the famous RAD 140. While RAD 140 is the stronger SARM, this one’s mild but the positive side is that you don’t experience side effects.

There is no disruption to any of the bodily functions. 

That’s precisely why lifters prefer Ostarine. Ostarine offers good results without any noticeable changes in the body. Of course, there is an increase in energy, mass, and athleticism. 

There are a variety of benefits of consuming Ostarine. Most importantly, it increases the overall strength and muscle mass. But did you know that Ostarine also helps you improve your bone health? Your joints will feel buttery smooth, and in return, you will be able to lift better too. There’s a chance you may not get injuries because it makes your movements smooth and stress-free. 

Ostarine is also said to be good for your heart health and also enhances insulin resistance. You can use Ostarine for both bulking and cutting phases. Lifters should use Ostarine for a six to ten-week cycle. Dosage should be 15 to 30 mg daily unlike RAD 140 in which the dosage is 20 mg.

Pros & Cons of RAD 140 and Ostarine

The Common Point – How are RAD 140 and Ostarine similar?

Ostarine and RAD 140 may have differences, but there is a common point. Both are SARMs and can be used for bulking up, but RAD 140 doesn’t help with cutting or losing weight. As for the side effects, RAD 140 leads to severe side effects, but there is one similarity between the two. 

SARMs work quite differently than usual anabolic steroids, but they will still lead to suppressed testosterone levels. Now, suppressed natural testosterone can cause different side effects like bone density loss, erectile dysfunction, insomnia, muscle weakness, depression, gaining weight, hair loss, and increased body fat. 

Although the side effects are almost non-existent in Ostarine, they're still there. Both Ostarine and RAD 140 show great potential in a controlled clinical setting. Additional research is required and a number of leading experts are working on it.

RAD 140 Vs. Ostarine: Which One’s Better?

When choosing between the two SARMs, you will be overwhelmed. However, the choice is pretty clear. Even though RAD 140 and Ostarine are popular and quite well-proven too, you can’t be making a bad decision if you select one of them. Both will offer good results. 

Hold that thought! In case you are thinking of putting on mass and wish to do it as quickly as possible, then RAD 140 is the way to go. 

Ostarine is a better pick for experimentation. It gives you all kinds of health benefits too. You can put on mass with it and also lose fat. 

If you are new to the world of SARMs, we would suggest you go for Ostarine. Both amateur lifters and expert lifters can use this safely without experiencing too many side effects. 

Overall, we find that Ostarine is safer and offers innumerable benefits to the lifter. Moreover, it can be used for both bulking and cutting, so it is indeed a good option with fewer side effects.

Summing Up

Ostarine and RAD 140 are both SARMs and there is a lot of debate going on out there. Every lifter has a similar body goal – they want to bulk up. Then, there are others who want to cut. 

Most of the SARMs will have a similar benefit. These Selective Androgen Receptor Modulators target different androgen receptors of the body. SARMs are not yet out there, and experts are conducting research in different parts of the world. 

Athletes would prefer SARMs over steroids because they’re safer. Hard-core use of steroids can be lethal for athletes; thus, SARMs are a poignant choice. In the case of the experimentation stage, we recommend using Ostarine as this one’s a milder variant and does not pose major health risks.


Are SARMs steroids?

SARMs are synthetic ligands and not anabolic steroids. SARMs can replace the androgens and produce favorable effects on the muscle tissues (quite similar to the anabolic steroids). 

Can you inject SARMs?

SARMs are administered orally, but specific supplements can also be injected if the lifter or any user chooses injectables. 

The only condition is these injectables shouldn’t carry any kind of negative effects. It could be toxic to the liver. So, if the injectables are safe and aren’t liver toxic, one can opt for this.

How to maintain the gains after the discontinuation of SARMs?

Maintaining the gaining results requires a few steps. You must invest in a muscle-building aid (natural). Stay consistent with the training and never follow any restricted diet plan. You must also consume enough protein and calories to maintain the gains.

Is Ostarine better than RAD 40?

RAD 40 is much stronger than Ostarine. Ostarine has lesser side effects as compared to RAD 40. Moreover, there are other health benefits of Ostarine, so it is certainly safer in terms of side effects and benefits. 

Also, anyone who is looking to experiment with SARMs should opt for Ostarine as it is milder.

Which is the best SARM for bulking up?

Both RAD 40 and Ostarine are good for bulking up. You need a smaller dose of RAD 40 because it's more potent. On the other hand, SARM is used for both bulking and cutting. The dosage of Ostarine will be higher as compared to the dosage of RAD 40.

Which SARM is suitable for both men and women?

Ostarine can be used by both men and women, but it isn’t the same case with RAD 40.

Is Ostarine (MK 2866) safe?

Ostarine MK 2866 is experimented with most frequently because it is a milder form of SARM. There is a chance you will not experience any side effects if you have real Ostarine for the experimentation procedure.

How does RAD 140 compare to other SARMs out there?

The muscles look quite veiny with the usage of RAD 140. With other SARMs, your muscles may appear soft, but with RAD 140, you will get a much more vascular aesthetic.
